Background technology
As everyone knows, terylene is hydrophobic high polymer, and its compound with regular structure can not ionization, does not have free electron again, and therefore the very easy static that gathers causes all consequences, has a strong impact on use value.At present, the method for eliminating terylene static mainly contains two kinds, and the one, surface treatment is promptly at the surperficial coated antistatic additive of fiber and fabric thereof; The 2nd, basic modification, promptly add antistatic additive at fibrous inside to give its antistatic property.Obviously, the former is because in processing, dyeing and finishing, washing and use, the antistatic additive that is modified at fiber surface loses easily, so antistatic effect often can not be lasting.Therefore, trend towards adopting the latter more and more to be paid close attention to produce persistent anti-electrostatic polyester fiber.
Antistatic additive can be divided into outside antistatic additive (temporary pattern antistatic additive) and inner antistatic additive (mixed milling type antistatic additive/permanent antistatic agent) two big classes according to using method.External antistatic agent is made up of micromolecular surfactant, contains hydrophilic radical and lipophilic group.Because antistatic additive and material itself are also not exclusively compatible, therefore can move to resin surface by material internal.Under certain damp condition, hydrophilic radical increases resin surface moisture, makes electrostatic charge be able to dissipation, thereby reaches the purpose that reduces its surface resistivity.The tradition antistatic additive has certain restriction service time in continuous consumption.Internal antistat can be processed by mixing and molding, adds the antistatic additive of capacity in material, forms the dense arrangement of one deck on the surface, and surface concentration is higher than inside, and hydrophilic radical becomes conductive layer towards air, constitutes the percolating network of a tool conductive capability.Compare external antistatic agent, the internal antistat pot life is long, so claim " permanent antistatic agent ".
The interior interpolation of single type antistatic additive such as Japan Patent JP47-36459 system adopts in the aliphatic alcohol polyethenoxy phosphate and is added on prepared fiber in the polyester resin, though it antistaticly has a persistence, effect is bad.And the polyster fibre that carries out compound antistatic additive compounded technology for the employing polyether compound mentioned among the CN85107888 and alkylsulfonate compounds in application (patent) number, though having overcome, this invention adopts the deficiency of adding antistatic additive in the single type, also provide a kind of and can produce antistatic efficient height and durable polyster fibre, but the process complexity.
